(1-1. Configuration)

First, a configuration of a display control device according to the first embodiment of the present technology will be described with reference to FIGS. 1 and 2. FIG. 1 is an appearance diagram illustrating a display control device according to a first embodiment of the present technology. FIG. 2 is a functional diagram illustrating a display control device according to the first embodiment.

The display control device 10 a according to the first embodiment of the present technology is an information processing device that enables an input operation to be carried out using a touch sensor. The display control device 10 a may be, for example, not only a cellular phone but also an information processing device such as a portable music reproducing device, a portable moving image processing device, a portable game machine, a personal computer (PC), a personal handyphone system (PHS), and a personal digital assistant (PDA).

A display unit 30 is disposed on a surface of the display control device 10 a. An operation unit 20 using a touch sensor and overlapping the display unit 30 is then disposed. The display control device 10 a may also have an operation unit 20 using buttons separate from the touch sensor. Users may perform operations on a display screen displayed in the display unit 30 to input desired operation information to the display control device 10 a. In addition, the display control device 10 a may control the contents of the display screen based on the input operation information. The display control device 10 a may control the displayed contents using a so-called graphical user interface (GUI).

When the user carries out the input operation using the touch sensor, the user may operate the display screen displayed on the display unit 30 by an operating body O to input the operation information. The operating body O may be a finger of the user, for example. Alternatively, the operating body O may be a stylus.

Next, referring to FIG. 2, the display control device 10 a mainly includes an operation unit 20, a display unit 30, an operation detection unit 101, a display control unit 103, a storage unit 105, and an output unit 107.

The operation unit 20 may be configured to include, for example, operation means for causing the user to input information such as a touch sensor, buttons, a mouse, and a lever, an input control circuit generating an input signal based on the user operation and outputting the input signal to the operation detection unit 101, and so forth. The display control device 10 a is a device that has at least the operation unit 20 using the touch sensor. The touch sensor used herein is a contact type touch sensor detecting a location of the operating body O in contact with the screen. Alternatively, the touch sensor used herein may be a non contact type touch sensor detecting a location of the operating body above the screen.

The display unit 30 may be, for example, a display device such as a liquid crystal display (LCD) device and an organic light emitting diode (OLED) display device. The display unit 30 may operate in accordance with control of the display control unit 103 to present the display screen to the user.

The operation detection unit 101 has a function of detecting operations input by a user based on input signals input from the operation unit 20. For example, the operation detection unit 101 may detect an operation of setting and changing the display area to be displayed on the screen within a predetermined image. For example, operations detected by the operation detection unit 101 may include a selection operation, a scroll operation, an enlargement operation, a reduction operation, a display area move operation, and so forth. The operation detection unit 101 may input information of the detected operation to the display control unit 103. When the user performs the operation using the touch sensor on the operation screen displayed on the display unit 30, the input signal is input to the operation detection unit 101 by the operation unit 20. The operation detection unit 101 may detect a location of the operating body based on the input signal. Operations that may be input on the respective operation screens and motions to be carried out by the operations are present in a corresponding way on the operation screen operated by the user. The operation detection unit 101 may refer to the operation information corresponding to the operation screen and determine a type of the operation input from a transition of the detected location of the operating body O. The operation detection unit 101 may input the operation information including the type of detected operation and the operation location to the display control unit 103.

The display control unit 103 has a function of controlling motions of the display unit 30. The display control unit 103 may control motions of the display unit 30 based on the operation information input from the operation detection unit 101. The display control unit 103 may determine the display area of the image based on the operation information input from the operation detection unit 101. The display control unit 103 may then control displaying the plurality of images such that the display area set within the image is displayed within the display screen for each of the images to be displayed within the display screen among the plurality of images. In this case, the display control unit 103 may cause the display area portion of the image to be enlarged and displayed within the display screen.

The storage unit 105 is a unit for storing data, and may include a storage medium, a recording device recording data on the storage medium, a reading device reading data from the storage medium, a removal device for removing data recorded on the storage medium, and so forth. Here, for example, a non-volatile memory such as a flash memory, a magnetoresistive random access memory (MRAM), a ferroelectric random access memory (FeRAM), a phase change random access memory (PRAM), and an electronically erasable and programmable read only memory (EEPROM), or a magnetic recording medium such as a hard disk drive (HDD) may be employed as the storage medium. For example, the storage unit 105 may store programs for controlling actions of the display control device 10 a or various data. In addition, the storage unit 105 may store content data including the plurality of enlarged images generated by the output unit 107.

The output unit 107 has a function of outputting the plurality of enlarged images as data different from the original data (the plurality of images that are not enlarged) based on the operation information output from the operation detection unit 101. For example, when depression of a button displayed in the display screen is detected, the output unit 107 may output the plurality of enlarged images at the time that the corresponding button is depressed. Data that is output at this time may be, for example, data that is cut and enlarged from the display area portion. Alternatively, data that is output at this time may be data of which the location information of the display area and the image correspond to each other. The output unit 107 may output the plurality of images in a form including information required to enlarge and display the same display area as that output when the plurality of images are displayed next time.

An example of the function of the display control device 10 a according to the present embodiment has thus been described. Each of the components described above may be configured using a general purpose member or circuit and may also be configured using hardware dedicated to the function of each component. In addition, the function of each component may be carried out by reading a control program that has described a procedure realizing the function of each component from a storage medium such as ROM or RAM and analyzing and executing the control program using a processor such as a central processing unit (CPU). It is thus possible to change the configuration to be employed as appropriate in response to the current technology level at which the present embodiment is embodied.

In addition, it is possible to create a computer program for realizing each function of the display control device 10 a as described above and mount the program on a personal computer or the like. In addition, a recording medium that has the computer program stored therein and is readable by a computer may also be provided. The recoding medium, for example, may be a magnetic disk, an optical disc, a magneto-optical disc, a flash memory, and so forth. In addition, the computer program may be distributed, for example, through the network without using the recording medium.

(1-2. Display Control)

FIG. 7 is a diagram illustrating an example of enlargement and reduction operations (pinch-in, pinch-out). FIG. 8 is a diagram illustrating an example of a display screen when an enlargement operation (pinch-in) has been carried out. FIG. 9 is a diagram illustrating an enlargement operation on a thumbnail image displayed by a display control device according to the first embodiment. FIG. 10 is a diagram illustrating an example of a display screen displayed by a display control device according to the first embodiment after an enlargement operation. FIG. 11 is a diagram illustrating an example of a display screen displayed by a display control device according to the first embodiment when a scroll operation is carried out after an enlargement operation. FIG. 12 is a diagram illustrating a display area move operation on a display screen displayed by a display control device according to the first embodiment. FIG. 13 is a diagram illustrating an example of a display screen displayed by a display control device according to the first embodiment after the display area move operation shown in FIG. 12. FIG. 14 is a diagram illustrating an example of a display screen displayed by a display control device according to the first embodiment when a moving image of a security camera is displayed. FIG. 15 is a diagram illustrating an example of a display screen displayed by a display control device according to the first embodiment after an enlargement operation on the display screen of FIG. 14 is carried out.

First, referring to FIG. 3, an example of the display screen displayed by the display control device 10 according to the present embodiment is shown. Here, an example of which the display control unit 103 causes a plurality of thumbnail images on which a soccer game has been recorded to be displayed on the display screen 302 by scrolling will be described.

The display screen 302 may include, for example, a plurality of thumbnail images Ti in a first display field 51. In FIG. 3, four images of the thumbnail images TI-1 to TI-4 are displayed. Hereinafter, the thumbnail images may be distinguished between the thumbnail image TI-1, thumbnail image TI-2, and so forth as necessary. However, when it is not necessary to particularly distinguish between the thumbnail images, the thumbnail images are denoted with the same reference TI. For example, when it is not necessary to particularly distinguish between the thumbnail image TI-1, the thumbnail image TI-2, and so forth, the thumbnail images are simply referred to as a thumbnail image TI. The thumbnail image TI, for example, may be an image that is displayed every predetermined time interval such as 5 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes, or the like. Alternatively, the thumbnail image TI may be an image at the time of start point of each chapter. For example, here, the thumbnail image TI is displayed every 15 seconds. In addition, the thumbnail image TI displayed in the first display field 51 may be a still image and may also be a moving image of a predetermined period that is repeatedly reproduced. For example, among the thumbnail images TI displayed in the first display field 51, the thumbnail image TI displayed at a location near the center of the screen may be a moving image and the other thumbnail images are still images.

In addition, the display screen 302 may include a second display field 53 in which any one of the thumbnail images TI is displayed to be larger than the thumbnail images TI displayed in the first display field 51. The image displayed in the second display field 53, for example, may be a thumbnail image TI displayed at a location near the center among the thumbnail images TI displayed in the first display field 51. The image displayed in the second display field 53 may also be changed when the thumbnail image displayed in the center of the first display field 51 is changed. In addition, the display screen 302 may include a scroll bar that scrolls the display of the thumbnail image TI.

Next, referring to FIGS. 4 and 5, how the scroll operation is carried out is illustrated. As shown in FIG. 4, the scroll operation may be performed by carrying out a so-called drag operation of moving the slider SL of the scroll bar included in the display screen 302 while the scroll bar is selected and then carrying out a so-called drop operation of taking off the slider SL at the destination as shown in FIG. 5.

Here, an enlargement operation carried out by the user will be described with reference to FIGS. 6 to 8. FIG. 6 illustrates a first example of the enlargement operation. For example, the user may enlarge and display the desired location by carrying out a double-tap operation of tapping the operation screen of the display control unit 10 a twice in succession. For example, at this time, the display control unit 103 may control the display using a predetermined enlargement ratio centered on a touch point of the double-tap operation.

Alternatively, as shown in A of FIG. 7, when the user carries out an operation of narrowing an interval between two touch points using two fingers (pinch-out operation), the display control unit 103 may reduce and display the display screen. At this time, the display control unit 103 may determine the location of the reduced display area based on the location of the touch points, and may determine the reduction ratio in response to the amount of change in interval between the touch points. In addition, as shown in B of FIG. 7, when the user carries out an operation of increasing the interval between two touch points using two fingers (pinch-in operation), the display control unit 103 may cause the display screen to be enlarged and displayed. At this time, the display control unit 103 may determine the location of the enlarged display area based on the location of the touch points, and may determine the enlargement ratio in response to the amount of change in interval between the touch points.

For example, FIG. 8 illustrates the state before and after the enlargement operation. As shown in FIG. 8, the display control unit 103 may cause the image of the display area determined based on the location of the touch points and the amount of change in interval between the touch points to be enlarged and displayed.

Here, the process returns to the display screen 302 of FIG. 3 again. The user carries out the enlargement operation on any (in this case, the thumbnail image TI-1) of the thumbnail images T1 displayed in the first display field 51 of the display screen 302. For example, the enlargement operation may be carried out by carrying out the pinch-in operation on the thumbnail image TI-1 displayed in the first display field 51 as shown in FIG. 9. The display control unit 103 determines the display area DA based on the pinch-in operation.

The display screen 308 after the enlargement operation is carried out is illustrated in FIG. 10. A portion corresponding to the display area is displayed in the thumbnail image TI to be displayed in the first display field 51 in the display screen 308. The display area is a portion of the thumbnail image TI-1 determined based on the enlargement operation as described above. Here, the size of the area for displaying one image of the first display field 51 has a predetermined value. The display control unit 103 may cause a portion of the thumbnail image TI to be enlarged and displayed such that the size of the display area DA portion is equal to the predetermined size. In addition, the display control unit 103 may cause a portion corresponding to the display area DA determined in the thumbnail image TI-1 to be enlarged and displayed for a portion of each of the thumbnail image TI-2, the thumbnail image TI-3, and the thumbnail image TI-4.

When the user carries out the enlargement operation on any of the thumbnail images TI displayed within the display screen, for example, the thumbnail image TI-1, the enlarged thumbnail image TI-1 is enlarged to display the display area determined based on the enlargement operation. In addition, a portion corresponding to the display area of the thumbnail image TI-1, is enlarged and displayed for each of the thumbnail image TI-2, the thumbnail image TI-3, and the thumbnail image TI-4.

In addition, the display area DA may be displayed overlapping the image displayed in the second display field 53. By means of the display, the user may understand what portion of the image is enlarged at the current point of time.

In addition, the display screen 310 on which the scroll operation is carried out on the first display field 51 in the enlarged display screen 308 is illustrated in FIG. 11. The display control unit 103 controls the display such that a portion of the thumbnail image TI-1, which is newly displayed in response to the scroll operation and corresponds to the display area of the thumbnail image TI-1, is also enlarged and displayed.

In addition, the user may carry out an operation of changing the display area DA, for example, a move operation. Referring to FIG. 12, the user may move the display area DA by carrying out a drag-and-drop operation on the display area DA portion on the image displayed in the second display field 53. When the user carries out the move operation, the thumbnail image TI of which the moved display area DA portion is enlarged is displayed in the first display field 51 as shown in FIG. 13. In addition, aside from the example that the display area DA is changed, a further enlargement operation, a reduction operation, and so forth may be employed.

As described above, according to the display control device 10 a of the present embodiment, when the user carries out the enlargement operation on any one of the displayed images, the corresponding display area DA portion is enlarged and displayed without carrying out the enlargement operation on each of the plurality of display images. In addition, a portion of the plurality of thumbnail images TI included in the content is displayed in the first display field 51 within the display screen. When the operation of changing the thumbnail image TI to be displayed among the plurality of thumbnail images Ti included in the content is carried out, a portion corresponding to the display area DA in the thumbnail image TI newly displayed in response to the change operation is also enlarged and displayed. An example of the operation of changing the thumbnail image TI to be displayed may include an operation of changing extraction conditions of the thumbnail image TI aside from the scroll operation described with reference to FIG. 11. For example, when the change operation is carried out such that the thumbnail image TI displayed every 15 seconds is changed to be displayed every 1 minute, a portion corresponding to the display area DA in the thumbnail image TI newly displayed in response to the change operation is also enlarged and displayed.

The user can thus enlarge the same location of each of the plurality of thumbnail images TI using the enlargement operation one time. As in the example described herein, it is possible to more efficiently find the portion at which the score changes in the program on which the soccer game is recorded by enlarging and displaying the score display portion.

The same location of each of the images may be focused and seen when the desired image among the plurality of images is found. For example, a moving image of a fixed point camera may be exemplified as another example of focusing and seeing the same location of each of the images.

Here, an example in which the display control device 10 a according to the present embodiment causes the moving image of the fixed point camera, that is, a moving image of a security camera, to be displayed will be described with reference to FIGS. 14 and 15. It is assumed that an unusual event has occurred at a safe that is continuously recorded by the security camera. When the point of time at which the unusual event that occurred at the safe is specified, it is necessary to check the image of the security camera focused on a portion near the safe. Here, when the display control device 10 a described above is employed, the display screen 316 of FIG. 14 is enlarged, and thus the enlarged display screen 318 displays a plurality of enlarged thumbnail images T1 enlarged in the first display field 51 as shown in FIG. 15. In addition, the display screen 318 may include a button B1 for storing data after enlargement. When the user operates the button B1, it is possible to store the data of the display area portion at the point of time at which the operation started as data separate from the original data. In addition, although the button B1 is illustrated herein, the present technology is not limited thereto, but may employ other operations corresponding to the operation of storing the enlarged image. For example, depression of the button installed on a main body of the display control device 10 a, selection of a menu displayed by depressing the button installed on the main body of the display control device 10 a, and so forth may be employed as the other operations.

2. Second Embodiment

Next, the display control device controlling the display based on the input operation from an external input device will be described with reference to FIGS. 16 and 17. FIG. 16 is a diagram illustrating a functional block diagram of a display control device according to the second embodiment of the present technology. FIG. 17 is a diagram illustrating an appearance example of the display control device according to the second embodiment.

The display control device 10 b according to the second embodiment of the present technology mainly includes an operation detection unit 101, a display control unit 103, a storage unit 105, and an output unit 107. The display control device 10 b according to the second embodiment differs from the display control device 10 a according to the first embodiment in that the operation unit 20 and the display unit 30 are not present.

For example, the display control device 10 b having a functional configuration as shown in FIG. 16 is an information processing device such as a desktop type PC shown in FIG. 17. In this case, among a display, a keyboard, and a mouse connected to the main body of the PC serving as the display control device 10 b, the display corresponds to the display unit 30, and the keyboard corresponds to the operation unit 20. The display control device 10 b is not limited to the PC. For example, the display control device 10 b may be a gaming machine. In this case, the operation unit 20 is a controller of the gaming machine.

The function of each component shown herein is the same as that of the display control device 10 a according to the first embodiment of the present technology, and thus the repeated description is omitted. In addition, the display control device 10 a according to the first embodiment detects the location on the screen at which the operation is carried out by the operating body O and then detects the operation information based on the location of the operating body, whereas the display control device 10 b, for example, operates the location of the pointer on the screen using the mouse and may thus detect the operation information based on the location information of the pointer.

An example of the function of the display control device 10 b according to the present embodiment is thus described. Each component described above may be configured using a general purpose member or circuit or may also be configured using hardware dedicated to the function of each component. In addition, the function of each component may be carried out by reading a control program that has described a procedure realizing the function of each component from a storage medium such as ROM or RAM and analyzing and executing the control program using a processor such as a CPU. It is thus possible to change the configuration to be employed as appropriate in response to the current technology level at which the present embodiment is embodied.

In addition, it is possible to create a computer program for realizing each function of the display control device 10 b according to the present embodiment as described above and mount the program on a personal computer or the like. In addition, a recording medium that has the computer program stored therein and is readable by a computer may also be provided. The recoding medium, for example, is a magnetic disk, an optical disc, a magneto-optical disc, a flash memory, and so forth. In addition, the computer program described above may be distributed, for example, through the network without using the recording medium.

In addition, in the embodiments described above, the display control device 10 a having the built-in operation unit 20 and the display unit 30 is described in the first embodiment. In addition, the display control device 10 b connected to the external operation unit 20 and the external display unit 30 is described in the second embodiment. However, the present technology may be applied to not only the examples described above but also various types of the information processing devices. For example, either of the operation unit 20 and the display unit 30 may be built in and the other may be installed externally.

3. Hardware Configuration Example

Next, an example of hardware configurations of the display control device 10 according to the first and second embodiments of the present technology described above will be described with reference to FIG. 18. FIG. 18 is a diagram illustrating an example of hardware configurations of the display control device according to the first and second embodiments of the present technology.

For example, the function of each component of the display control device 10 described above may be embodied using the hardware configuration shown in FIG. 18. That is, the function of each component is realized by controlling the hardware shown in FIG. 18 using the computer program. In addition, the type of the hardware is arbitrary, for example, may include a handheld terminal such as a personal computer, a cellular phone, a PHS, a PDA, a gaming machine, or various information appliances. Note that “PHS” refers to a personal handy-phone system. In addition, “PDA” is an abbreviation for “personal digital assistant.”

As shown in FIG. 18, the hardware mainly includes a CPU 902, a Rom 904, a RAM 906, a host bus 908, and a bridge 910. In addition, the hardware includes an external bus 912, an interface 914, an input unit 916, an output unit 918, a storage unit 920, a drive 922, a connection port 924, and a communication unit 926. Note that “CPU” is an abbreviation for “central processing unit.” In addition, “ROM” is an abbreviation for “read only memory.” “RAM” is an abbreviation for “random access memory.”

For example, the CPU 902 acts as a processor or a control device, and controls all or some of actions of the respective components based on various programs recorded on the ROM 904, the RAM 906, the storage unit 920, or the removable recording medium 928. The ROM 904 acts to store programs read in the CPU 902 or data used for the operation, and so forth. For example, the program read in the CPU 902 or various parameters that are properly changed to execute the program are stored temporarily or persistently in the RAM 906.

For example, these components are connected to each other through the host bus 908 in which data may be transmitted at a high speed. Meanwhile, the host bus 908 is connected to the external bus 912 in which data is transmitted at a relatively low speed through the bridge 910, for example. In addition, the input unit 916 may employ, for example, a mouse, a keyboard, a touch panel, a button, a switch, a lever, and so forth.
